<p>We have a reasonable if not perfect tagging system for a router
to assess (and make assumptions) about the quality of a road for
various types of vehicle in BEST CASEĀ conditions. motorway versus
track, tracktype, asphalt versus gravel being the main ones.<br>
</p>
<p>From a router point of view it would be nice to dynamically place
routing penalties on roads or stretches of road according to
temperature, snow, rain, side wind (and ?). Simplistically, input
"snow" and pick up from OSM tags advising "often impassable in
snow" or "snow chains advised in winter" and then the router can
decide how much penalty to apply given projected conditions and
vehicle type.</p></div></blockquote><div>Do routers "read" such things as flood-prone, intermittent & seasonal?</div><div><br></div><div>Thanks<div><br></div><div>Graeme</div></div><br></div></div>
